摘要:
The present invention is directed to a method for preparing microcapsules which comprises:preparing an aqueous dispersion or emulsion of a hydrophobic oily core material containing a polyvalent isocyanate, a polyvalent isothiocyanate, or an adduct thereof, having an anionic moiety; andforming capsule walls around the droplets of said oily core material.
